    Abstract: A lithium supplementing material includes Li5MO4 and a semiconductor oxide on a surface thereof, where M includes at least one of Fe, Ni, Mn, Ru, Cr, Cu, Nb, Al, or Mo. In this application, the lithium supplementing material containing the semiconductor oxide is used, which can significantly enhance electronic conductance of the lithium supplementing material, reduce polarization, and greatly improve a specific charge capacity of the lithium supplementing material. Applying the lithium supplementing material to a positive electrode of an electrochemical apparatus can effectively increase an energy density of the electrochemical apparatus, and also improve rate performance and cycle stability.

    Abstract: Embodiments of the present application relate to a solid electrolyte and a preparation method thereof, and an electrochemical device and an electronic device comprising the same. The solid electrolyte of the present application includes a solid electrolyte material being represented by the chemical formula of Li1+2x−2yMyGa2+xP1−xS6, where M is selected from the group consisting of Sr, Ba, Zn, Cd and a combination thereof, 0≤x≤0.2 and 0≤y≤0.05. Embodiments of the present application provides a solid electrolyte having good stability with lithium and ionic conductivity by forming the solid electrolyte using lower cost solid electrolyte materials and optimizing the material composition and a crystal structure thereof. At the same time, this also reduces the manufacturing costs of the solid electrolyte, and improves the structural stability of the solid electrolyte.
